TUG ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No. 227,738, dated May 18, 1880. Application filed March 19, 1880. (ModeL) To all whom it may concern:

Be it known that I, SILAS (JoURTRIGH'r, of Hookers Station, in the county of Fairfield and State of Ohio, have invented a newand useful Improvement in Tug Attachments, of

which the following is a specification.

This invention consists in a novel construction, arrangement, and combination of a metallic frame and case, a pair of bolts, a sliding head or follower, and a number of rubber springs and interposed washers, for preventing the sudden shock to either the horse or .the vehicle in starting a load or striking an obstruction. In the accompanying drawings, Figure 1 is a longitudinal sectional view of a tug attachment embodying myimprovements. Fig. 2 is a transverse section taken in the line 00 w of Fig. 1. Fig. 3 is a detail view.

Similar letters of reference indicate corresponding parts. 7

A representsthe portion of the tug which is toward the hame or collar, and A the portion toward the vehicle. The portion A is attached 2 5 to a box or case, B, by means of bolts or screws passing through it and through ears 1) formed at the end of the box or case. The portion A is attached to a plate, 0, (an edge view of which is shown in Fig. 3,) by means of bolts or screws passing'through it and through ears 0 formed on the plate.

The box or case B is of oblong form, and has its two sides and two ends closed and its top and bottom open. In this box or case is 3 5 another box or case, D, also of oblong form, but having its top and bottom and two sides closed and its two ends open.

In the case D a number of rubber cylinders, E, are carried. The diameter of each cylinder is nearly equal to the depth of the case D and 4.0 half its width, said width being double the depth. The length of each cylinder may be equal to or greater or less than its diameter, as may be preferred. The cylinders E are arranged in two rows 4,5 in the case D, with metallic washers G interposed between them, and the case D is placed in the case B. Two bolts, J J, are then passed through the plate 0, thence through holes in one end of the case B, thence through the cyl- 5o inders E and washers G, and finally through holes in a head or follower, K, outside of which the ends. of the bolts are secured by nuts 13 i. The partsA and A are then attached, as before described, and the tug is ready for use.

The cylinders E act as springs in taking off the jar and preventing the shock when starting suddenly or striking an obstruction.

- If desired, an oblong block of rubber may be used instead of two cylinders; but I prefer to use the cylinders.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the tug A A of the plate 0, boxes or cases B and D, bolts J J, rubber cylinders E, metal washers G, follower K, and nuts 43 i, as shown and described, for the purpose specified.
